How to send data by POST method to https://steamcommunity.com/tradeoffer/TRADE_OFFER_ID/accept?

Question

PHP

You need to send data using the POST method, when loading the page, to the address https://steamcommunity.com/tradeoffer/TRADE_OFFER_... to accept the offer on Steam. Tried to send using various methods, both via cURL and via file_get_contents , but no result. Even the standard form submission returns a null page. Maybe someone has experienced sending POST data to accept offers from Steam?

Answer 1

To accept offers, at least you need to be logged in under the profile from which you want to accept. As an option, screw cookies from the browser to the curl (for example, you can steal them using Cookie Manager ) First
you need to make sure that you are at least logged into your account profile... use. This is how curl_setopt($cl, CURLOPT_COOKIEJAR, 'cookie.txt'); curl_setopt($cl, CURLOPT_COOKIEFILE, 'cookie.txt'); , where cookie.txt is your stolen account cookies from the browser, which are in the same folder with the php script launch file.
Then parse at least your inventory to check the performance of these cookies and your code (the test is to return the page with your profile to you)
